开源一个sheet表格类

可以建立表格，输入内容，居中显示

#include <iostream>

#include <conio.h>

#include <string>

#include <graphics.h>

using namespace std;

class sheet{

public:

    sheet(int l=5,int c=5,int width=80,int highth=40,int posx=0,int posy=0);

    //行数，列数，行宽，列宽，起始位置x，y

    void put_txt(int x,int y,char *s);

private:

    int col,lin,col_high,lin_width,pos_x,pos_y;

};

sheet::sheet(int l,int c,int width,int highth,int posx,int posy)

{

    col=c;

    lin=l;

    lin_width=width;

    col_high=highth;

    pos_x=posx;

    pos_y=posy;

    int grax,gray;

    grax=col*lin_width;

    gray=lin*col_high;

    int i,j;

    for(i=0;i<=grax;i+=lin_width)

        line(i+pos_x,0+pos_y,i+pos_x,gray+pos_y);

    for(j=0;j<=gray;j+=col_high)

        line(0+pos_x,j+pos_y,grax+pos_x,j+pos_y);

}

void sheet::put_txt(int x,int y,char *s)

{

    outtextxy((x-1)*lin_width+20+pos_x,(y-1)*col_high+8+pos_y,s);

}



int main()

{

    initgraph(800,600);

//  sheet a(15,6,100,30,20,20);

    sheet a;

    string s="张三";

    a.put_txt(2,2,s);

    getch();

}
